▶ Background and Motivation

 The electronics and optoelectronics have been promising future research topic. Especially, Each low dimensional semiconductor has outstanding characteristics about those in the materials world. 2D materials without atomic bonds in the Z-axis are superior in electron characteristics. Because TMDCs  have complementary optical absorption properties as well as electronic properties, those are also called as materials of dream. Our laboratory will demonstrate electronic and optoelectronic devices based on 2D materials with noble physical properties and break through the limitations that current industry faces.

▶ Large Scale TMDC growth

     using Metal-Organic Chemical Vapor Deposition

Metal-Organic CVD growth  provides a unprecedented direction of high-quality monolayer TMDC film for the integration of multiple device patterning with different 2D material compositions and electrical properties on single substrate. Metal Source and Gas are precisely Controlled by individual MFCs

▶ 2D/Quantum Dots(QDs) Hybrid Optoelectronics

The 2D-0D hybrid optoelectronic system maximizes the photodetector characteristics such as responsivity (R), Detectivity (D*) employing the advantages of the light absorption of quantum dot material and the high mobility of two-dimensional material.

▶ 2D Hetero-structure Electronics
